The Proper Way To Conduct a Patch Test Before Brow Services
Posted by Troy Barker on

When providing brow services, ensuring your client’s safety should always come first. One of the most critical steps in building trust and avoiding any mishaps is conducting a patch test. This quick, simple procedure can save you and your client from an unpleasant experience and ensure their brows look flawless without any irritation.
But how do you conduct a patch test the right way? Keep reading to learn the proper steps and best practices to conduct a patch test for brow services.
What is a Patch Test?
A patch test is a precautionary measure performed before applying certain brow products to a client’s skin. It provides insight into how your client’s body might react to a product.
By applying a small amount of product to a discreet area of skin, you can check for potential allergic reactions or sensitivities before proceeding with the full treatment. This is a good practice for any beauty salon and an essential safeguard for your client’s safety and your business reputation.
Why Conduct a Patch Test?
Imagine spending hours perfecting a client’s brows only for them to call you the next day with redness, itching, a rash, or worse. Allergic reactions to brow products, such as tint, henna, or lamination solutions, can happen to anyone, even if they’ve used similar products before.
The skin around the brows is particularly sensitive, making it especially important to confirm whether a product is compatible with your client’s skin. A patch test also reassures clients you prioritize their safety, earning you their trust and potential future patronage.
Who Needs a Patch Test?
In most cases, everyone can benefit from a patch test, but it’s especially vital for certain groups. First-time clients and clients trying a new brow service or product they haven’t used before will definitely require testing.
Even your regulars might need a patch test if you’re switching to a new brand or formulation. Remember, skin can change over time due to factors such as hormones, medications, or health conditions, so err on the side of caution and perform a quick patch test.
How to Perform a Patch Test
Want to perform a patch test like a pro? Follow these steps to ensure your client’s safety and confidence.
Step 1: Choose the Test Area
Start by selecting a discreet area of your client’s skin to apply the product. Common areas include behind the ear or in the bend of the elbow, as these spots typically encounter fewer environmental irritants and offer a reliable reaction result.
These areas are also easy to cover if a reaction does occur, so your client can go about their day without feeling self-conscious. Make sure the skin is clean, dry, and free of any products, such as lotions or perfumes, that could interfere with the results.
Step 2: Apply the Product
Using a clean cotton swab, applicator, or brush, apply a small amount of the brow product to the chosen test area. Be precise, using the product exactly as you would during the service.
If the product requires mixing, activation, or dilution, follow those instructions carefully before applying. This ensures the test mimics the exact conditions of the full treatment. Explain this step to your client so they understand the importance of accuracy.
Step 3: Wait
Now comes the waiting game. Allow the products to rest for 15-20 minutes. If you notice a reaction during this time, wash off the product immediately with a clean cotton pad or cloth and don’t proceed with the full treatment.
If this period passes without a noticeable reaction, the client should still wait 24-48 more hours before scheduling a full treatment to ensure they don’t experience any later reactions. During this time, advise them to avoid washing, rubbing, or scratching the area, as this could distort the results or cause irritation unrelated to the product.
Step 4: Remove the Product
After the 15–20-minute waiting period, gently remove the product using water or a mild cleanser. This step is essential to ensure any lingering residue doesn’t skew the results. Observe the area while removing the product in case any irritation becomes apparent during this step.
Step 5: Assess
Finally, evaluate the results. Examine the test area for any redness, swelling, itching, or other signs of irritation. Encourage your client to share any discomfort they may have felt during the waiting period, even if there’s no visible reaction.
If the skin appears normal and your client didn’t experience any issues, you can proceed with confidence. However, if a reaction occurs, explore alternative products or treatments tailored to their sensitivities. This step ensures their safety and reinforces your salon’s professionalism and commitment to their well-being.
Other Best Practices for Promoting Client Comfort
Beyond just conducting a patch test, here’s some more tips you can practice to help your clients feel more comfortable and confident in your services.
Use High-Quality Products
High-quality products minimize the risk of adverse reactions. We recommend selecting options from trusted brands such as Elleebana, which use ethical sourcing and premium formulations. Explore highly-rated products such as the Elleeplex Profusion lash lift and more for your services. Your clients will notice the difference.
Educate Your Clients
Take a few minutes to explain what a patch test is and why it’s important. Many clients see it as an extra (and unnecessary) step, but once they understand the risks it can prevent, they’ll thank you for your diligence.
Document Everything
Keep a record of each patch test, including notes on what product you used, where you applied it, and the results. This is especially important for first-timers or if any concerns arise after treatment.
Repeat Patch Tests Regularly
Our skin changes as we age and from other outside factors. If your client previously had a successful patch test with a product but reports skin changes or sensitivities, conduct another one just to be safe.
Make it Part of Your Policy
Incorporate patch tests into your pre-service consultation for new clients or when introducing new products. Consistency builds trust and establishes you as a diligent, professional brow technician.
Building Safer Brow Services
Patch tests may seem small in the grand scheme of your brow services, but knowing the proper way to perform a patch test can make a world of difference. These practices ensure the safety and comfort of your clients and cement your reputation as a thoughtful, professional technician. By following the above steps and best practices, you can deliver beautiful brows with confidence—and keep your clients coming back for more.
